One component polyurethane foam is hardened by humidity in the air once it has been sprayed from the can. In the case of dry season or working place, the foam may droops and flow down because of the shortage of air humidity. So, spray the water properly on all adhered parts before and after work.


If the gas is exhausted, the foam could not be sprayed. One component polyurethane foam is sprayed with the gas. But, if you use the foam in an upright position, the gas would be exhausted in advance and there would be much residual volume. So, shake the can at least 20 times before use and apply the foam with the can positioned upside down (outlet downwards).


One component polyurethane foam is hardened by humidity in the air once it has been sprayed from the can. In the case of enclosed space, it may have not been hardened well because it is airproof. So, it may be formed by bubbles and holes. So, to have better work result, spray the water properly on all adhered parts and applied foam and in case of applying foam in multi layers, spray the water on each layer, too.


The discharge pressure of the product can be decreased when the temperature is under +20°C. Especially, the product may have not been sprayed in the winter because of it. So, please store the product inside to be able to keep the optimal temperature and prevent this problem. Also, if the discharge pressure was decreased, please put it in lukewarm water of 30 ~ 40°C and use the foam.

 

Warning! Do not heat it directly by using the heater or stove as there is a risk of explosion.


In this case, the inside of foam gun or valve may have been hardened by residues. Please check the foam gun if it can be sprayed by using cleaner. If it do not have a problem to use, please check the inside of the valve and remove the residues that was hardened by using the tool like tweezer.
